SASH-FAiSTENER.

SPECIFICATION forming part of Letters Patent No. 417,868, dated December24, 1889.

Application filed September 3, 1889. Serial No. 322,880. (No model.)

To (0Z5 whom, it may concern.-

Be it known that I, IIEMAN D. JANES, of Cleveland, in the county ofOuyahoga and State of'Ohio, have invented certain new and usefulImprovements in indow-Sash Fasteners; and I do hereby declare thefollowing to be afull, clear, and exact description of the invention,such as will enable others skilled 1 1n the art to which it pertains tomake and In the accompanying drawings, Figure l is a side elevation asseen from the inside of the window. Fig. 2 is an elevation in transversesection. Figs. 3, 4, and 5 are enlarged elevations in detail.

A and 13 represent, respectively, the upper I and lower sash separatedin the usual manner by stops a. In Fig. 1 is shown two fasteners answerthe purpose, although two are preferable, for reasons hereinaftermentioned.

sides and bottom of the upper sash. Each fastener is constructed asfollows:

. C is a small metal plate having an integral rim 0, the plate and rimconstituting substantially a casing or housing. This housing is set intothe upper sash far enough to something more than clear the lower sash inopening the window. The central portion of plate 0 is cut away or cored,leaving a rectangular opening, in which operates with an easy fit leverD, the latter constituting the fastener proper. The lever shown is ofcast metal and is cut away top and bottom on the front side thereof,leaving square shoulders and lips D D respectively, above andbelow. henlever D is flush with plate O, lips D D are adapted to extend behind andengage the rear side of the plate. (See Fig. 4:.)

lip D terminates in lugs d, that extend laterally behind plate 0 andconstitute a sliding pivotal support for leverD, whereby the latterThese fast- I The location of these fasteners is shown more clearly inFig. 1, being respectively near the 1 The upper may be raised or lowereda limited distance and may be swung outward, as shown more clearly inFig.

In case lever D were constructed of wrought metal the ends thereof.could be offset rearward to form lips D D A rearwardlyprojecting toe clis flush with the extreme lower end of lever D, these two members beingpreferably integral. The lower face of the toe should be curved 011 aradius from lugs d asa center. This toe serves as a stop to preventlever D from sliding down too far when the lever is swung outward by theaction of its spring; otherwise the levers might wedge in between thesash in opening the window. A small hole a, preferably metallined, isusually bored in the wood to receive toe (1, when leverD is swung backto the position shown in Fi t. g

E is a spring fastened by means of the upper securingscrew 0, the screwpassing through a hole in the spring and in the housing, and passingalso through a hole in the metal block 0, the latter serving merely tofill up the space between the spring in the wood and to give a firm seatto the spring. The spring bears against the inner side of lever D,causing the latter to swing forward, as shown in Fig. 3, in case thelever is in its elevated position,so that lip D does not engage thehousing.

F is a small metal angle-plate fastened 011 the top edge of the lowersash in position to receive the thrust of lever D, the uprightleg ofthis angleplate serving as a stop to prevent lever D from swingingoutward too far. Depressions d on the face of lever D are for thefingers, whereby the lever may be raised or lowered. lVhen the sash arein their normal or closed position with levers D resting on plates F,and the upper shoulders of these levers consequently engaging thehousings, (see Fig. 2,) a very strong fasteningis had, it beingremembered that the housings are set into the upper sash, by reason ofwhich it would be impossible to open the window without breaking thesash, and consequently making more noise than would be agreeable to aburglar seeking to enter the house. Of course two fasteners hold thesash more securely than one fastener, and are preferable for otherreasons, hereinafter mentioned.

When it is desired to open the window, levers D are pressed back againstthe action of their springs, and are then slid downward until lips Dhook behind the housing, thereby fastening back these levers andrendering them inoperative, whereupon the sash may be raised or loweredat pleasure.

In closing the window, by raising levers D to disengage the lower lipsfrom the housing the recoil of the spring will press levers D outward totheir seats on plates F, thus fastening the window-sash; but suppose itis desired to lower the uppersash a short distance for the purpose ofventilation, and to leave the sash in such position over night. For thispurpose notches l) are provided on the outside of the lower sash inposition to engage levers D when the upper sash shall have been lowereda predetermined distance, these notches being preferably metal lined.

In unfastening the device, so that the upper sash can be lowered, leversD may be pushed back only far enough to clear the lower sash, in whichposition toes (I rest on the edges of the housing, and in such positionof parts levers D cannot move downward in the housing, and when theupper sash is moved downward the recoil of the springs causes levers Dto enter notches 19, thereby preventing the upper sash from moving anyfarther downward. In such position of parts the upper sash of coursecovers notches b, and consequently levers D are inaccessible. In suchposition of parts the lower sash can be raised the distance that theupper sash has been lowered, but in so doing will carry with it theupper sash, and, except this movement of the two sash together, the sashare as firmly locked as if both were closed, and the raising of thelower sash an inch or two would not materially help a burglar in gainingadmittance to the house. When the upper sash is again raised to itsnormal position, levers D, by the action of their springs, automaticallyfasten the two sash in their closed position. In case of two fastenersbeing employed notches b are preferably made at different elevations.Suppose notch 1) (shown at the right hand in Fig. 1) to be located so asto admit of lowering the upper sash an inch, and suppose notch h at the1 left hand to be located so asto admit of low- 5 ering the upper sashtwo inches. If both le- 1 vers D were left free, of course the lever atithe right hand would engage its notch when the. sash was lowered aninch. If, however, this lever were fastened back in the manner alreadydescribed, the sash could be lowered two inches, or until the lever atthe left hand had engaged its notch Z). It will be seen, therefore, thatthe employment of the two sash admits of lowering the sash more or less,as required, according to the relative position of the respectivenotches b.

There are several varieties of window-fasteners that are secured to thetop of the checkrails of the sash by one or more screws, andconsequently it does not require a great force to push up the lowersash, thereby drawing out the screw, and this can be done making butlittle, if any, noise.

WVith my improved fastener in position the raising of the lower sashwould involve a general wreck of the window, and a burglar would hardlyapply such force as would necessarily thwart his object by reason of theresultant crash.

WVhat I claim is 1. A window fastener consisting, essentially, ofhousing, spring-actuated locking-bar having vertically-sliding pivotalengagement with the housing, such locking-bar having a depending lip forengaging the housing with the depression of the locking-bar, whereby thelatter is held rearward against the action of the spring, substantiallyas set forth.

2. In window fasteners, in combination, housing, spring-actuatedlocking-bar having a vertically-sliding pivotal attachment with thehousing, substantially as indicated, a rearwardly-proj ecting toeconnected with the locking-bar, such toe being adapted to ride on thehousing with the vibrations of the lockingbar, substantially as setforth.

3. The combination, with housing having a sunken seat in the upper sash,spring-actuated locking-bar adapted to engage the lower sash, notches inthe outer face of the lower sash for receiving the locking-bar when theupper sash is lowered a predetermined distance, substantially as setforth.

4. The combination, with housing and locking-bar, substantially asindicated, of spring E and metal block 0, substantially as set forth.

In testimony whereof I sign this specificatio11,in the presence of twowitnesses, this 6th day of April, 1889.
